Abstract: An optical method and system for measuring characteristics of a sample using a broadband metrology tool in a purge gas flow environment are disclosed. In the method a beam path for the metrology tool is purged with purge gas at a first flow rate. A surface of the sample is illuminated by a beam of source radiation having at least one wavelength component in a vacuum ultraviolet (VUV) range and/or at least one wavelength component in an ultraviolet-visible (UV-Vis) range. A flow rate of a purge gas is adjusted between the first flow rate for metrology measurements made when the source radiation is in the VUV spectral region and a second flow rate for metrology measurements made when the source radiation is in the UV-Vis spectral region. The system includes a light source, illumination optics, collection optics, detector, a purge gas source and a controller. The purge gas source is configured to supply a flow of purge gas to a beam path in the light source and/or illumination optics and/or sample and/or collection optics and/or detector. The controller is configured to control a flow rate of the purged gas flow in response to an output signal from the detector.

Abstract: A method through which a more rapid detection of Helicobacter pylori in a gaseous sample is practicable, in which the 13C content is measured only until a minimum number of measurement values of the 13C content meets a standard deviation to be specified. The known 13C urea breath test has become established for clinical diagnosis for detecting Helicobacter pylori infections and known methods for detecting Helicobacter pylori provide that each method step corresponds to a fixed, specified time, which is disadvantageous, especially for performing a large number of such tests.
